Oil and gas are the most traded commodities on the planet; they are also the chief causes of the most grievous harm our species has yet faced, the burgeoning climate crisis. Bill McKibben is the Schumann Distinguished Scholar at Middlebury College and a founder of Third Act, which organizes people over the age of 60 to work on climate and racial justice. He examines how the export of hydrocarbons, in particular, has become an enormous threat to efforts to rein in greenhouse gasses. It explores the role that America – the world’s biggest exporter of gas – plays in this ongoing catastrophe. And it looks at the role that non-tradeable commodities – sunshine and wind – play in easing this crisis. Series: "UC Berkeley Graduate Lectures" [Science] [Show ID: 40220]
